[rdo-list] [TripleO] adding bridge mappings

Hi, I want to add bridge mapping to the compute nodes so that I can add provider networks to it. I tried the following but that created the bridges also on the controller nodes *NeutronBridgeMappings: "datacentre:br-ex,physctrldown;br-ctrldown,physctrlup:br-ctrlup,physdatadown:br-datadown,physdataup:br-dataup"* *NeutronFlatNetworks: "datacentre,physctrldown,physctrlup,physdatadown,physdataup"* I then tried the following but that caused an error during deployment *NeutronBridgeMappings: "datacentre:br-ex"* *NeutronFlatNetworks: "datacentre,physctrldown,physctrlup,physdatadown,physdataup"* *NovaComputeExtraConfig:* * neutron::agents::ml2::ovs::bridge_mappings: "datacentre:br-ex,physctrldown;br-ctrldown,physctrlup:br-ctrlup,physdatadown:br-datadown,physdataup:br-dataup"* ERROR was *| 18f2a192-e051-414e-9ca0-7b3c62aceec3 | overcloud-ComputeNodesPostDeployment-iakgqhkkmoya-ComputePuppetDeployment-exnug4z4zwy6 | CREATE_FAILED | 2016-12-08T13:18:42 | None | f5e28803-a4d1-4718-b3c0-1e82473a7cda |* *| f5e28803-a4d1-4718-b3c0-1e82473a7cda | overcloud-ComputeNodesPostDeployment-iakgqhkkmoya | CREATE_FAILED | 2016-12-08T13:17:56 | None | 41b8b97f-3974-4ec5-ace8-495a33300d29 |* *| 41b8b97f-3974-4ec5-ace8-495a33300d29 | overcloud | CREATE_FAILED | 2016-12-08T12:59:05 | None | None |* How can I have the bridges created only on the computes nodes??
